drew strikes me as the kind of guy who was unaccustomed to and unprepared for the level of passion dory would begin to inspire in him starting in season 2. this newfound intensity, combined with his natural passivity and cowardice, keeps drawing him back again and again against his better instincts and I think he really did mean it when he screamed he was “addicted” to her. and on dory’s side, what she wants the most in the world is to be significant. i wouldn’t go so far to say she cultivates his dependence, but she does enjoy it and knows how to play it. together, they’re almost uniquely posed to make each other worse. drew is too weak willed to reign dory’s delusions in, or even stop tacitly supporting them by helping dory deal with the consequences. dory is too egotistic to really encourage drew to grow a spine. AND layer on top the familiarity that comes from a multi-year close friendship followed by a mediocre but cordial relationship. i really think they DO love each other but the versions of each other they liked are no longer people that exist.
